Upconverting microgauges reveal intraluminal force dynamics in vivo.

The forces generated by action potentials in muscle cells shuttle blood, food and waste products throughout the luminal structures of the body. Although non-invasive electrophysiological techniques exist, most mechanosensors cannot access luminal structures non-invasively. Here we introduce non-toxic ingestible mechanosensors to enable the quantitative study of luminal forces and apply them to study feeding in living Caenorhabditis elegans roundworms.

Meeting report: patient and caregiver recommendations for a mobile health application for paediatric systemic lupus erythematosus.

Paediatric systemic lupus erythematosus (pSLE) management and research could be enhanced by a mobile health application (app); however, no app designed for pSLE is currently available. A development and design committee comprising of patients, parents/caregivers and other stakeholders met to inform development and design of an app specific for pSLE. This meeting report summarises the group's discussions and recommendations that could help create a useful and desirable app or mobile health tool for the pSLE community.
